STOVE.

Specification of Letters Patent.

Patented Nov. 21, 1911.

Application fi1ed March 29, 1910. Serial No. 552,167.

To all whom it may concern:

Be it known that I, JACOB MnRsEnnAU, a citizen of the United States, anda resident of Port Chester, in the State of New York, have inventedcertain new and useful Improvements in Stoves, of which the following isa specification.

My invention relates to gas or oil stoves, and particularly to the fluesthereof, which serve to connect the stove with a chimney or otherdischarge point out of the room in which the stove is located, and whichserve to carry away the products of combustion generated by the flame ofthe stove.

The object of the invention is to provide a flue which shall eflicientlyserve the purpose of carrying off into the chimney the products ofcombustion, affording free and unobstructed passage therefor, but whichshall permit any back draft or downward air current which may pass fromthe chimney into the flue to pass out and away from the stove and thusprevent the draft from disturbing or extinguishing the flame of thestove.

The invention consists in the novel construction, arrangement andcombination of parts hereinafter particularly described and shown in theaccompanying drawings.

In the accompanying drawings, Figure l is a side view, partly insection, of my invention showing also the chimney connection, Fig. 2 isa horizontal section of the same on the line 22 of Fig. 1, Fig. 3 is aback view of the same, Fig. 4 is a vertical section on the line 44 ofFig. 3, Fig. 5 is a top view of the same, and Fig. 6 is a detail view ofthe burner.

In gas or oil stoves as ordinarily used, where the products ofcombustion are discharged into a chimney flue or into the outer air, aserious difliculty is encountered in the liability of the flame to bedisturbed or even extinguished by back drafts or downward currents ofair in the chimney.

In carrying my invention into effect, in order to construct a flue whichwill allow the upward passage of the products of combustion but preventthe passage of back drafts into the gas stove, I provide a flue piece,the main part of which, designated 10 in the accompanying drawings, issemicylindrical in shape, and the lower part, designated 11, isflattened and bent inward toward the stove as shown in Figs. 1 and 4.

The lower edge of the flue is provided with a flange 12 (see Fig. 1)which is adapted to engage with the edge of the flue opening in the backportion 18 of the stove, thus supporting the flue vertically, it issteadied and held in an approximately upright position by hook-pieces 13(see Fig. 1) which are secured by screws 14 to the inside of the flueand the hooked ends of which engage with the upper side parts of theedge of the flue opening. The lower end of the semicylindrical part ofthe flue is open below, as shown at 15.

In Figs. 1, 8 and 4, 16 designates a part of the back of the stove,which rests on the flange 17 of the portion 18. The part 16 slopesoutwardly, and lies adjacent to the open front of the semi-cylindricalpart 10 of the flue. An annular top or collar 19 is provided, which fitsover the top of the flue, resting partly upon the flange 20 and beingsecured thereto by a screw 21, and partly upon the sloping back piece16. A portion of the top of the stove is shown in Fig. 1, beingdesignated 22. The upper part of the top or collar 19 is adapted toreceive one end of a pipe 23, the other end of which may lead into achimney flue 24.

In preferred form, I secure to the sloping back-piece 16, by a bolt andnut or in any suitable manner, a back-draft deflector 25. It is notnecessary, however, that this deflector be of the exact shape or formshown in the drawings, and I do not limit myself to the same, or todeflector separate from the flue.

The operation and also the advantages of my invention are obvious fromthe foregoing desoription of the construction.

l/Vhile the products of combustion have a free and unobstructed passagefrom the burner through the flue, passing below the lower edge of thedeflector 25 and then upward, any back-draft or downward current of airpassing from the chimney into the flue does not follow the same path,but is deflected and passes down and out into the room but is preventedfrom reaching and disturbing or extinguishing the flame of the stove.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is as follows:

1. A flue for gas stoves and the like, comprising a passage for theproducts of com bustion, the end portions of which are comparativelycontracted and the middle portion of which is comparatively enlarged,said flue being provided with an inlet at the lower end communicatingwith the stove, an outlet at the upper end, an intermediate downwardlyopening outlet, and deflecting means in said passage adapted to directinto said intermediate outlet and away from said inlet, downward orbackward currents in said passage way, said deflecting means comprisinga battle-plate secured by its upper portion to the wall of the flue.

2. A flue for gas stoves and the like, comprising a passage for theproducts of combustion, the end portions of which are comparativelycontracted and the middle portion of which is comparatively enlarged,said flue being provided with an inlet at the lower end communicatingwith the stove, an outlet at the upper end, an intermediate downwardlyopening outlet in the enlarged portion of said passage, and deflectingmeans in the enlarged portion of said passage adapted to direct intosaid; intermediate outlet and away from said inlet, downward or backwardcurrents in said passage way, said deflecting means comprising abaffle-plate secured by its upper portion to the wall of the flue.

In witness whereof I have hereunto signed my'name this seventh day ofMarch 1910, in the presence of two subscribing witnesses.

JACOB MERSEREAU.
